Abstract

The invention relates to a routing updating method and system for a dynamic network. The method includes: obtaining a changed link in the dynamic network; updating the topology table of the dynamic network according to the two end nodes of the link; using the Dijkstra shortest path algorithm according to the updated topology table of the dynamic network Updating the routing table of the first end node and the routing table of the second end node; determining the node to be updated to obtain a routing update set; judging whether the ith node is included in the routing update set; if so, Updating the topology table of the dynamic network stored in the i-th node, and calculating the routing table of the i-th node according to the updated topology table of the dynamic network; if not, updating the i-th node A topology table of the dynamic network is stored. The invention can solve the global optimal routing updating problem in any dynamic network environment, and reduce the calculation load caused by routing updating.

Description

technical field [0001] The present invention relates to the field of dynamic networks, in particular to a route update method and system for dynamic networks. Background technique [0002] The concept of dynamic network widely exists in a variety of network systems, such as the failure of nodes or links in the Internet, the movement of nodes in terrestrial Ad Hoc networks, and the high-speed movement of satellites in satellite networks, all of which can lead to changes in the topology of the network. . Routing is the basis of network data transmission. Once the network topology changes, data transmission based on the original topology may fail if the corresponding routing calculation and update are not performed. Therefore, routing update in dynamic network environment is the key problem to solve dynamic network data transmission. At present, the routing update of dynamic network mainly includes reactive routing update and active routing update strategy. [0003] The reac...
